Title: Image pickup device
Inventor: OKADA HIDEO
IPC: H04N5/335
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To make the constitution small by reducing an optical path length. SOLUTION: By arranging plural double refraction boards 33-35 sequentially along an optical system of a lens 23, a variable spatial filter 24 placed between the lens 23 and an image pickup element 26 is constituted. The double refraction boards 33, 34 are moved around an optical axis 22 of the lens in terms of angular displacement to change a spatial frequency characteristic and the double refraction board 35 is moved in terms of angular displacement around an axial line 38 for an image shift orthogonal to the optical axis of the lens to operate an image shift. In a 1st operation mode where low resolution is obtained, the variable spatial filter causes a space frequency limit effect to serve as an optical low pass filter.  In a 2nd operation mode where high resolution is obtained, the variable spatial filter applies synthesis arithmetic processing to each image output of the image pickup element 26 before and after the double refraction board 35 is tilted by an image shift mechanism 37 so as to decrease a spatial frequency limit effect, that is, to spread a variable spatial frequency pass band to a high frequency band and so as to improve the resolution.

Title: Diazo copying material
Inventor: NISHIZAKI TOSHINAGA
IPC: G03C1/52
Filed: 1985-02-19
Abstract: PURPOSE:To prevent an image from being plagiarized or forged by forming either of character parts and other parts in dots to 120 lines per inch and the other part to 80 lines per inch. CONSTITUTION:Dot printing has two methods; (1) character parts of a latent image consist of dots of 80 lines per inch and other parts of dots of >=120 lines per inch and (2) the character parts of the latent image consists of dots of >=120 lines per inch and other parts of dots of <=80 lines per inch. When an image is formed by using a diazo copying material and copied by electrophotography, the character parts of the latent images are embossed in black by the method (1) and in white by the method (2). In both cases, the latent image can not be discriminated visually. When a diazo copy is taken, a copy image is developed clearly. Further, the use of gold or silver ink make hidden parts inconspicuous and the character parts are reproduced efficiently by specular surface reflection. Consequently, images are prevented from plagiarized or forged.

Title: Phase locked loop
Inventor: TODA YOSHIFUMI
IPC: H03L7/107
Filed: 1983-02-25
Abstract: PURPOSE:To speed up the phase locking when out of synchronism occurs in a PLL circuit with a small sized circuit by connecting diodes in anti-parallel with a series resistor connected between input and output of a filter in the PLL circuit using a lag filter or a lag/lead filter as a loop filter. CONSTITUTION:When out of synchronism occurs and an output voltage of a phase comparator 2 is increased, the forward resistance of the diode D1 or D2 becomes smaller, and a series resistance between the input and output of the lag/lead filter is decreased equivalently. Thus, the damping factor xsi is increased and the phase locking time is reduced. When the phase locking state is obtained, an output voltage of the phase comparator 2 becomes a constant value and a potential differnce across the series resistor R1 becomes very small, then the resistance of the diodes D1, D2 becomes very large, the series resistance is expressed as the R1, the band of the filter is narrowered and a good S/N is obtained. Thus, the phase locking time from the state of the out of synchronism is reduced by having only to use the diodes D1, D2.
